Allow me to contribute to the bug report.
Playing as Byzantium on VH/VH settings on year 1106.
Nikaia cannot upgrade from large town status due to lack of building walls option in the city scroll. I think that you've already encountered this bug in a previous version for another faction, not sure which.
In the recruitment report scroll, when recruiting heavy spearmen their respectable image is as large as the size of the image in the description scroll, not the tiny icon of the usual recruited units
Some unit cards for example spearmen, lancers are not purple but grey. I wouldn't know whether it is a bug or intentional, thus I report it.
Bucuresti and Bagdad are missing their special character s and g respectably when opening the city scroll or when being referred in the turn report scrolls. Not certain if it is happening with other city names though.
Last and not least a what seems buggy behaviour of the AI. Nearly all Italian factions (Sicily, Papal States and Venice) siege Kerkyra settlement (Corfu Island on the map) and after one turn has passed they offer peace in a quite profitable -for my empire- way (about 8-10k gold).
Cheers for now!Thank you for releasing this nice mod!!!
